Quanum head tracker and Jeti Tx

Here is a bit of information for those of you who are using the Quanum head tracker together with a Jeti transmitter. I have been using the head tracker together with my DC16 for the last two years but there has been some problems. The servos has had some stuttering and has made some glitchy movements. But yesterday I connected my Quanum head tracker to my new DS-12 Special edition tx and now they work perfectly together. Both transmitters has essentially the same software so there has to be something new on the hardware side in the new transmitter.
